A smаll reseаrch spаcecraft is rоtating slоwly in deep space. It has twо identical instrument booms folded close to its body. The spacecraft extends both booms outward, and its angular speed decreases to 60% of its original value. Assume the net external torque is negligible.A student states:“The lost angular speed means that both angular momentum and rotational kinetic energy were lost.”Evaluate this statement.In your response:Explain what happens to the spacecraft’s moment of inertia when the booms extend.Use angular-momentum conservation to determine how the final moment of inertia compares with the initial moment of inertia.Determine whether rotational kinetic energy remains constant.Explain how rotational kinetic energy can change even though angular momentum is conserved.Identify the source or destination of the energy associated with extending the booms.Predict what would happen if the booms were pulled back inward.Explain whether an observer inside the spacecraft and an observer outside it would agree about the conservation of angular momentum.
